' FEEDING MECHANISM.

To all whom it mm concern:

Be it known tits t I, HENRY WEBER, a citizen of the United States,residing at 'Ghicage, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Feeding Mechanism, ofwhich the following is a specification. v

My invention relates to feeding mechanism and has for its primary objectthe provision of improved feeding mechanism which shall have meanswhereby one wire may be fed at regular lntervals, and a second wire fedat any predetermined intervals.

With the above and otherpbjects in view this invention consistssubstantially in the combination, arrangement, and construction of partsall as hereinafter described, shown in the accompanying drawings whichform apart of this specification and illustrate the preferred embodimentof my inventlon, and more particularly set forthirf the subjoinedclaims. v

In the drawings: Figure 1 is aside elevation of a device embodying myinvention,

illustrating in conjunction therewith a holder and wire reels supportedthereby. Fig.2 is a detailedview of the device shown in- Fig, 1 andillustrates in dotted lines a position which the parts assume inoperation. Fig. 3 is a section taken approximately on line 3-3 of Fig.2. Fig is a section taken approximately on line 44: of Fig. 2. Fig. 5 isa section taken .approximately on line 5-,?) of Fig.2. Fig. 6 is apartial. section taken approximately online 66 of Fig. 2. Fig. 7 is asection taken on line 7-7 of Fig. 5. Fig. 8- is a perspective view of aratchet and disk illustrated in Figs. 1, 2, 4c, and .5. Fig. 9 1s a planviewof a piece of work stapled by the device illustrated in the figuresand embodying my invention. 1 Reference numeral 10 indicates generally astapling head of any suitable construction and embodying a frame plate11, a cammed wheel 12, a feeding lever 13, a feeding framel, a cutter15, a former 16, ahammer 17, an anvil 18, a supporter 19, and asupporter block 20. The type of Stapling head illustrated in thedrawings, 1s one well known in the prior art, and in it the cammed wheel12 operates the feeding frame 14 by contact with thefeeding lever 13.the feeding lever reciprocating the feed- 1 staples settingSpecification of Letters Patent.

ing frame upontwo guide ,rods21, the

cammed wheel 12 also reciprocates the cutter 15, the former 16, thehammer 17, and the anvil 18, the supporter19 being operated by contactwith the hammer. In Fig. 1 there is illustrated a reel holder 22carrying reels 23 and 24. which deliver wires 25' and 26 respectively tothe stapling head 10.

Retrograde movement of the wires 25 and i ,26 is prevented by means ofany suitable holding device, generally indicatedby ref:

erence numeral 27 The path of movement of the feeding frame 14, whichpath-may be varied by rotation of a handle 28, is illustrated by meansofdotted lines in Fig. 2. This feeding frame: carries two feeding clutches29 and 30, which normally engage the wires 25 and 26 respectivelyduringthe forward or feeding movement of the frame 14 and feed the wiresto the cutting, forming, and driving mechanism. Upon the backwardmovement of the feeding frame 14:, that is, from the position shown indotted lines in Fig.2 to that shown in full lines, the clutches 29 and30 slip over the wires 25 and26 without moving them.

In the present embodiment of my inven- '1 2 tion it is illustrated incombination with a stapling head such as described above, and itincludesmeans for idling the wire clutch 30 during a predeterminedinterval such, for example, as that illustrated in Fig.9 wherein, afterthe setting of the two staples illustrated at the left end of the lineof staples in the work, the clutch 30 was idled during an intervalsufiicient to allow the clutch 29 to feed seven staples; in other words,my invention provides meanswhereby -in'con-. junctionwith a single lineof 'staples an eX- tra staple may be fed to the setting mechanism at'intervals predetermined bythe op-' 1 erator. In Fig. 9 the work operatedupon I is indicated by reference numeral 31 and in I it, in theadjustment of parts illustrated in the drawings, the apparatus hassetstaples nine times, beginning with setting twostaples, 32 and 33, thensetting seven single 32, and upon the ninth operation, again two staples32 and 33," the staples 32 being fed from the wire 25, and the staples33 from the wire 26. The present invention is of great utility in thatit provides means for double stapling'the ends' of a seam. To accomplishthe idling of the clutch 30 1 form thereon an extension 34' and insuitable relation to the extension I provide upon the feeding frame 14 apivot pin 35, upon which is mounted for rotation a disk 36, providedupon its outer face with a ratchet 37 having in the present adjustmentof parts nine ratchet points 38: the disk 36 and ratchet 37 are fixedwith respect to each other and both rotatable about the pivot pin 35.The disk carries upon its peripheral surface the extension 34 andnormally prevents the clutch 30 from engaging the wire 26. The disk isprovided with any suitable number of notches, the present adjustment ofparts necessitating the use of two such notches 39 and 40. ,Whenever,during the rotation of the disk, the extension 34 engages one of thenotches in the disk.

the succeeding forward or feeding movement of the feeding frame '14 willfeed not only the wire but also the wire 26, for the reason that thedescent of the extension 34into the notch of the disk permits the clutchto act upon the wire 26-to feed it. The mechanism illustrated in thedrawings is adjusted to set staples in groups of nine settings and inevery group to set nine single staples and two extra staples. Thenumberof extra staples set by ,the machine will,

however, in all cases be controlled by the number of-notches cry of thedisk '36,. the extra staples being formed from the wire 26.

To accomplish the rotation of the disk 36 a dog 41 is provided which, asthe feeding frame 14 moves forward to the dotted position shown in Fig.2, engages one of the ratchetpoints 38 and turns the ratchet and diskpartially about the pivot pin 35. To accomplish the complete rotation ofthe disk 36, as many engagements between the ratchet 37 and the dog 41are necessary as there are ratchet points 38 upon the ratchet. A slidebar 42 is mounted for horizontal'movement within the block 20, themovement being accomplished by means of a pivot 43, an eccentric 44mounted for oscillation'upon the pivot and engaging an aperture 45provided in the bar 42." As 1s shown in Fig. 5 the dog 41 is pivoted asat 46 upon one end of to thebar 42. The cam 44 is provided with anextension 47 which carries a pointer 48 and is provided with a handledset screw 49. In an are having the pivot 43 for a center is provided aseries of apertures 50 in the block 20 for engagement with the set screw49 and suitable graduations 51 corresponding to the apertures 50 areprovided upon the outer face of the block 20, the gradua tions inthe'present embodimentof the invention being numbered from 5' to 9 andindicating in each instance the number of ratchet points 38 upon theparticular 'disk 36 which the operator has set upon the pivot pin 35. Inthe'present adjustment of parts there are. nine ratchet pointsillustrated provided in the periph-' upon the ratchet 37, and inconsequence thereof the cam 44 has been moved until the pointer 48registers with the graduation 9, and the set screw 49 has been placed inengagement with the hole 50 which corresponds to the graduation 9. Thissetting of the cam 44 positions the slide bar 42 at v the extreme innerend of its path of movement and properly positions the dog 41 forengagement with the ratchet 37 when the ratchet has, as is illustratedin Figs. 2 and 8, nine points. If a lesser number ofpoints is desiredupon the ratchet, for instance five, the cam 44 is oscillated to movethe dog to- Ward the feeding frame 14. The position which the extension47 then assumes is illustrated in dotted lines in Fig. 1, wherein it isseen that the pointer 48 registers with the graduation 5 upon the block20. This adjustment'of the dog 41 is necessary, in order that it mayproduce a greater angular movement at each reciprocation of the feedingmechanism corresponding to the greater are covered by each tooth on theratchet 37. Upon the former 16 (see Fig.7) are provided an upper stud 52and a lower stud 53, these studs engaging an extension 54 upon the dog41 and oscillating the dog during the time that it engages the ratchet37 to cause it to positively turn'the ratchet; during the downwardmovement of the former the stud 52 engages the extension 54 andoscillates the dog upwardly to turn the ratchet, and during the upwardmovement of the former the stud 53 engages the-extension 54 and returnsthe dog to the position shown in dotted lines in Fig. 2.

Considering the partsto be positioned as illustrated in full lines inFig. 2, the operation of the present invention is as follows: Theextension 34 has dropped into the notch contact between the cammed wheel12, and the feeding lever 13 moves the weeding frame 14 and the clutches29 and 30 forward into the position shown in dotted lines. This motionfeeds suflicient wire to form two staples. As the feeding frame 14completes its forward stroke the dog 41 engages a notch of the ratchet37, following which the former 15 descends to form staples, causing theupper stud 52 to engage the extension 54 of the dog and throw thedog,upward into contact with one of the ratchet points 38. This upwardmovement of the dog turns the ratchet 37 and disk 36 through one-ninthof a circle and causes the extension 34 to rise from the notch 39 to theperiphery of the disk 36, this latter movementarrestin'g any grippingeffect of the clutch 30 upon the wire 26. The feeding frame 14reciprocates to the position shown in full' lines in. Fig.2, and therise of the former brings the lower stud 53 into contact with extensionfeed of the wire 25 the dog 41 turns the disk 36 through one-ninth of acircle. Upon the eighth forward movement of the feeding frame 14,however, the notch 40 is presented to the extension 34, which descendsinto it so that when the feeding frameis returned into the full lineposition it will, upon its ninth forward movement, feed forward bbthwires 25 and 26. Following each forward movement of the feeding frame 14the cutter, former, hammer, and anvil have performed their functions,each being constructedto handle two wires instead of one, and staples 32and 33 have been set into the piece of work 31 in the manner illustratedin Fig. 9. Obviously, as many notches as desired may be provided in thedisk 36, and as'each notch comes into proper position it will be engagedby the extension 34, causing at the next forward movement of the feedingframe 1 1, a feed of both wires to the cutter. In the manufacture ofarticles such as strawboard boxes, it is frequently necessary to doublestaple the ends of the seam of the box, binding-the seam between theends by single staples. It will readily be seen that by positioning thenotches '39 and 40 approximately one-ninth of a circle apart the seam inthe work 31, which requires stapling at nine points, will, if thestapling is begun when the extension34 is in engagement with the notch39, be double stapled at its ends, or at its'first and ninth staplepoints, and single stapled therebetween. It has been said that the seamin the work 31 requires staples at nine points. This is, of course, an

arbitrary requirement of commerce, but, should it be desired to stapleit at five points, for instance, instead of nine, and to double staplethe end points of the seam, a disk 36 would be provided and a ratchet 37thereupon, having five ratchet points 38 instead of nine, and thenotches 39 and 40, instead of being approximately one-ninth of a circleapart would be approximatelyone-fifth of a circle apart. From thisexplanation it will be understood what was meant above by settingstaples in groups of ninesettings and it will be readily understood,also, that while a disk of any size may be used having any suitablenumber of ratchet points for a given kind of work, my feeding mechanismmay be run continuously in a seam and caused to set extra staples at anydes1red intervals along that seam, regardless of the number of points inthe seam to be stapled.
